Fusulinid.

Van Möller, 1878. The Fusulinidae is a family of fusulinacean foraminifera from the upper Carboniferous (Lower Pennsylvanian, Morrowan) to the Upper Permian ( Guadalupian ), tests of which are fusiform to subcylindrical with walls of two to four layers.

This assemblage comprises 11 species of six genera, including Verbeekina, …Like their relatives—starfishes, sea urchins, sea cucumbers, and brittle stars—crinoids are echinoderms, animals with rough, spiny surfaces and a special kind of radial symmetry based on five or multiples of five. Crinoids have lived in the world's oceans since at least the beginning of the Ordovician Period, roughly 485 million years ago.By comparing the fusulinid species diversity and genus diversity with the relative sea-level curves, it can be inferred that during the Gezhelian and Asselian stages, fusulinid species diversified rapidly while sea level rose slowly; however, during the Wordian stage, the number of fusulinid genera increased rapidly while the sea level ...Benthic Foraminifera. 1.
